    Abstract: A first device associated with a second device in a wireless network, the first device comprising at least one station (STA) affiliated with the first device and a processor coupled to the at least one STA, the processor configured to perform a relay operation for a second STA that relays a frame between the second STA and a third STA, determine a change in an operational status of the first STA that is indicative of an overload condition of the first STA, determine to suspend the relay operation for the second STA based on the operational status, and transmit, to the second STA, a relay suspension message that indicates a suspension of the relay operation for the second STA.

    Abstract: Methods and apparatuses for reconfiguration of setup links between multi-link devices (MLDs). An access point (AP) MLD comprises APs and a processor. The APs each comprise a transceiver configured to transmit on a link setup with a corresponding STA of a non-AP MLD. The APs are affiliated with the AP MLD for ML operation on the setup links. The processor is configured to generate a reconfiguration ML element that indicates affiliated APs that are to be removed from affiliation with the AP MLD. The transceivers are configured to transmit the reconfiguration ML element to the corresponding STAs of the non-AP MLD. The processor is configured to determine whether any of the affiliated APs that are to be removed remain affiliated after transmitting the reconfiguration ML element, and to update the element to indicate the remaining affiliated APs that are to be removed. The transceivers of remaining affiliated APs are configured to transmit the updated reconfiguration ML element to the corresponding STAs of the non-AP MLD.

    Abstract: Methods and apparatuses for setup, management and use of relay devices in a wireless local area network. A relay device includes a transceiver and a processor operably connected to the transceiver. The transceiver is configured to form a first link with a wireless access point (AP) and a second link with a wireless non-AP station (STA). The processor is configured to determine to perform a relay control action comprising (i) setup of a relay connection by which the relay device will relay traffic between the AP and the STA over the first and second links, (ii) teardown of the relay connection, or (iii) advertisement of a capability of the relay device to support the relay connection, and to generate a control message including an indication of the relay control action. The transceiver is further configured to transmit, to at least one of the AP and the STA, the generated control message.

    Abstract: The following methods and apparatuses are provided which enable an AP MLD to indicate to one or more non-AP MLDs a recommended wake-up time for them on one or more links. The recommended wake time, in some embodiments, may continue for at least one STA over a prescribed number of intervals. Features are also provided for a STA to request a wake-up time recommendation to an AP, along with rules for the STA to obey. In one aspect of the disclosure, an AP sends a wake time recommendation element (WTRE) in a beacon interval. Rather than an immediate wake time, the WTRE includes a prescription recommending that one, more or all stations defer their wakeup times to a recommended wake time.

    Abstract: Embodiments of the present disclosure provide methods and apparatuses for obtaining timing information and performing a time offset adjustment for target wake time (TWT) operations in a wireless network. The apparatuses include a first communication device comprising a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to transmit, during a target wake time (TWT) setup phase, a TWT element including a request for information on a traffic delay of a second communication device and receive the information on the traffic delay. The processor is configured to determine a time offset to adjust a start time of a next TWT interval based on the information on the traffic delay.
